Method and system for coordinated scheduling based on cell priority

A method for coordinated scheduling based on cell priority, which is applied to a system using coordinated multiple point transmission (CoMP) technology, comprising:

• performing priority sequencing on each coordinated cell according to historical and/or current information of each coordinated cell;
• and
• successively finishing scheduling of each coordinated cell in an order according to priority from high to low;
• wherein,
• the historical information comprises one or any combination of following information:
• service volume, business intensity and type of served service of the present coordinated cell;
• the current information comprises one or any combination of following information:
• number of the user to be scheduled, current channel status information and data type of the user in the present coordinated cell;
• wherein,
• when the method is applied in a centralized coordinated network,
• the step of successively finishing scheduling of each coordinated cell in an order according to priority from high to low comprises taking any coordinated cell or one coordinated cell confirmed according to service volume or business status in each coordinated cell in the network as a central control cell, which finishes the scheduling of each coordinated cell, and sends the scheduling result to each coordinated cell respectively;
• when the method is applied in a distributed coordinated network,
• the method further comprises each coordinated cell sending the historical and current information of the present cell to all other coordinated cells, and meanwhile, each coordinated cell also receiving the historical and current information of the cell sent by other coordinated cells;
• the step of performing priority sequencing on each coordinated cell according to historical and/or current information of each coordinated cell comprises each coordinated cell performing the priority sequencing according to the historical and/or relevant information of all coordinated cells;
• the step of successively finishing scheduling of each coordinated cell in an order according to priority from high to low comprises:
• a high priority coordinated cell, after finishing the scheduling, notifying all low priority coordinated cells of the scheduling result;
• and the low priority cell receiving the scheduling result sent by the high priority cell.
